Well

- in my build i soon realised that
![](./images/smilies/spacer.gif)
£1500 for itb's was out of my reach so as im mechanically minded and lucky enough to have the facilities i firstly made my own inlet manifold but the itb's i used on that manifold were way to big so i ended up ditching that and brought a twin 40/45 dcoe carb inlet manifold, i had 2 40dcoe webbers that were shot as carbs but the bodies and throttle linkage was good so i gutted all the venturies out, all the jets, everything bar the throttle linkage and butterflies.

I then got the old choke restrictions and venturies and got them counter boered out to exactly 39mm
![](./images/smilies/spacer.gif)
- once this was done i re fitted them to the mouths of the carbs which gave me a nice smooth inlet track
![](./images/smilies/spacer.gif)
- that was my throttle bodies made!! The next obstical was getting a tps to go on the carbs.

after a quick google search i found a company called webcon who made tps systems especially designed for dcoe carbs!!! RESULT! So instead of spending
![](./images/smilies/spacer.gif)
£1500 i realistically ended up spending
![](./images/smilies/spacer.gif)
£200 for some itb's that do exactly the same job.

Alright they dont look quite as nice but it enables you to have throttle body performance/consitansy whilst keeping costs down.

As for mapping
![](./images/smilies/spacer.gif)
- stand alone it the best.
![](./images/smilies/spacer.gif)
Looking back i wish i had gone that route but instead i went with the greddy emanage which i think is the best alternative to a full stand alone.

I never had any real trouble with it at all but little niggly things like sending the std ECU to malaysia to get the rev limit moved to 9,200rpm was a pain in the ass and also i would have loved to be able to map the car on TPS only
![](./images/smilies/spacer.gif)
- not TPS and MAP as this would have made the idle perfectly smooth and driveability would be much improved!!

- if you wanna pm me i can give you some info on what i used and what i didnt
![](./images/smilies/spacer.gif)
- also some probs i found along the way.
![](./images/smilies/spacer.gif)
If you are thinking of keeping stock ecu and just using piggy back then i know a man in holland who can remove your rev limit and disable the map function so it only runs on tps!!
![](./images/smilies/spacer.gif)
(he can only do it on blue top ecu's where as mine was a red top and he couldnt get the eprom for it
